JAMES GILMORE, OF DE VITT, IOWA.

FIRE-wooD-sAwlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 333,848, dated January 5, 1886.

Application filed October 13, 1885.

To all whom it may concern.-

Be it known that I, J .Inns GILMORE, a citizen of the United States, residing at De Witt, in the county of Clinton and State of Iowa,have invented certain new and useful Improvements in Fire-Vood-Sawing Machines; and I do hereby declare the lfollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to firewood-sawing machines; and it has for its object to produce a light, yet strong, substantial, and durable machine which can be worked by hand, foot, or steam power, though I have illustrated it for operation by hand-power alone; and it consists in the parts and combinations of parts hereinafter described and claimed.

In the drawings forminga part of this specication, Figure 1 is a perspective view of my machine, and Fig. 2 is a side elevation of the same.

Similar letters refer to similar parts throughout the several views.

The su pporting-frame is made of iron,and is composed oftwo horizontal beams, A, two legs, A', at one end, joined together by a cross-piece, B, and brace-bars B. The other end ofthe frame is supported by an adjustable frame, C,which is pivoted to the beams A, and which carries a handle, c, by which it may be adjusted at a more or less acute angle to the beams A, and thus raise or lower the forward or saw end of the frame to accommodate logs of agreater or less diameter. To the upper side ofthe beams Aare secured two uprights,D, which are braced apart by a rod, d, and which support the sawcarrying frame by means of the bar e, acting as a pivot, passing through the horizontal frame E and said uprights. The bars composing the frame E are joined at their lever end by a bar, and at their other end carry the upright or swinging frame F by means of the rod f, which is passed through the bars of the swinging frame, and through the ends of the bars forming the horizontal frame E, the ends of said bars being cut out, so as to clamp the bars of the upright frame F, to permit the swinging movement of said frame. Io the lower end of the swinging frame is secured,by

means of clamping-plates g, the saws G, the

clamping-plates being pivoted to said frame.

the bars to accommodate logs of varying size.

To the ends of the beams A,I secure the sawguide H, which is provided with slots h, for the saws G to run in. I also form aslot in the brace-bar I. Pins or retaining-wedges K pass through the ends of the beams A and into-the log which is being operated upon, so as to hold it steady and prevent rolling. I connect to the center bar of the swinging frame F the end of a pitman, L, said pitman extending back, and being connected, by means of a removable wrist pin, Z, to a double split crank, M, said crank being provided with perforations, so that the throwr of the pitman may be lengthened or shortened by moving it along said crank. 'Io one of the shafts N is secured a pinion, O,which meshes with a gearwheel, P, said gear-wheel being carried by a short shaft jonrnaled to one of the beams A, While the other shaft N carriesatly-whecl, R. I show a crank-handle, S, for revolving the short shaft that carries the gear-wheel P; but it may be operated by a belt and pulley or by a treadle.

Projecting upward from one side of one of the beams A is a bar or npright,T,having a series of perforations, and from the horizontal frame E extends a lever, U, said lever having a handle formed on its end,and being provided with a perforation at a short distance from said handle, through which may pass a pin, u. By means of pin u and the perforations in the lever U and upright T, I am enabled to raise or lower the entire frame by simply raising or lowering the lever, and thus always keep the saws working level.

If desired, the frame B, being pivoted to the beams A, may be moved to the position shown in broken lines in Fig. 2, and thus lower that end of the frame of the machine. I may use as many saws as I desire by inserting bars in the swinging frame to support the same. (See bar in dotted lines, Fig. l.)

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isM

IOO

U, secured to the frame E and adjustably se cured to the upright T, the swinging fra-nie F, pivotally secured to frame E, the saws G, adjustaloly and pivotallyseeured to frame F, the saw-guide H, a pitnian,and means for driving the same, all as and for the purpose set forth.

3. A firewood-sawing machine comprising the following instrumeutalities: a main frame, an adjustable support therefor, a slotted braceloar, a slotted saw-guide, retainingpins, a perforated upright, T, a lever, U.- a horizon- 4tal frame, E, pivoted to uprights D, a swinging frame, saws, adjustably pivoted to the lower end of said swinging frame, a pitman pivotally secured to one of the bars of said frame, a double split ora-nk to which the pitnian is adjustably secured, the shafts N, pinion O, secured to one of said shafts, and y- Wheel R to the other, the gear-Wheel l?, and crank-handle S, all as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
